Title: Dump truck end gate locking system
Inventor: CORNELL DWAYNE HOWARD
IPC: B60P1/267
Filed: 1999-07-30
Abstract: A dump truck end gate locking system includes a dump truck having a chassis and a cargo box which pivots between a transport position and a dumping position. The cargo box has an end gate. A sensor is provided for sensing when the cargo box is in the transport position. A locking member is provided having a locked position engaging the end gate and an unlocked position disengaged from the end gate. A drive mechanism for the locking member is coupled to the sensor. The drive mechanism moves the locking member to the locked position to secure the end gate when the sensor indicates the cargo box is in the transport position. The drive mechanism moves the locking member to the unlocked position to release the end gate when the sensor indicates the cargo box has moved from the transport position to assume a dumping position.

Abstract: In a three-phase DC-to-AC inverter including, for driving each leg of the load, a controlled power driver such a pulse-width modulated field-effect transistor (FET) or insulated gate bipolar transistor (IGBT) pair, an estimator for estimating the current in each leg of the load. A low-resistance leg resistor is connected in series in the lower leg of each transistor pair. The voltages across the leg resistors are applied to two differential amplifiers to generate two discrete voltage difference values that are transmitted to an estimator. The estimator solves specified differential equations using suitably interconnected combiners, integrators, amplifiers and multipliers, or discrete digital equivalent or programmed computer equivalent, to derive a value for the estimated current in each leg of the load.

Title: Dynamic synapse for signal processing in neural networks
Inventor: LIAW JIM-SHIH
IPC: G06N3/06
Filed: 1998-06-11
Abstract: An information processing system having signal processors that are interconnected by processing junctions that simulate and extend biological neural networks. As shown in the figure, each processing junction receives signals from one signal processor and generates a new signal to another signal processor. The response of each processing junction is determined by internal junction processes and is continuously changed with temporal variation in the received signal. Different processing junctions connected to receive a common signal from a signal processor respond differently to produce different signals to downstream signal processors. This transforms a temporal pattern of a signal train of spikes into a spatio-temporal pattern of junction events and provides an exponential computational power to signal processors. Each signal processing junction can receive a feedback signal from a downstream signal processor so that an internal junction process can be adjusted to learn certain characteristics embedded in received signals.

Title: Communications localization system
Inventor: MALONEY JOHN E
IPC: G01S5/12
Filed: 1998-01-16
Abstract: Replica correlation processing, and associated representative signal-data reduction and reconstruction techniques, are used to detect signals of interest and obtain robust measures of received-signal parameters, such as time differences of signal arrival and directional angles of arrival, that can be used to estimate the location of a cellularized-communications signal source. The new use in the present invention of signal-correlation processing for locating communications tranmitters. This enables accurate and efficient extraction of parameters for a particular signal even in a frequency band that contains multiple received transmissions, such as occurs with code-division-multiple-access (CDMA) communications. Correlation processing as disclosed herein further enables extended processing integration times to facilitate the effective detection of desired communications-signal effects and replication measurement of their location-related parameters, even for the communications signals modulated to convey voice conversations or those weakened through propagation effects. Using prior, constructed signal replicas in the correlation processing enables elimination of the inter-site communications of the signal representations that support the correlation analyses. Reduced-date representations of the modulated signals for voiced conversation, or for the variable components of data communications, are used to significantly reduce the inter-site communications that support the correlation analyses.
